Complicated retroperitoneal diverticulitis presenting with abscess and acute limb ischemia.

This case highlights a rare presentation of diverticulitis of the sigmoid colon with perforation into the retroperitoneum complicated by abscess, vertebral osteomyelitis and acute lower extremity ischemia. A late 40-year-old man presented to an emergency department with acute ischemia of his left lower extremity. He was tachycardic with a leucocytosis, an unremarkable abdominal exam and a pulseless, insensate and paralysed left lower extremity.

Evaluation of a Military Global Health Engagement Mission for Critical Wartime Surgical Specialty Readiness.

Introduction: Surgical volume at Military Treatment Facilities (MTFs) has been gradually decreasing for roughly the past 2 decades. The Knowledge, Skills, and Abilities (KSA) Clinical Readiness Program linked surgical volume and readiness using a tool known as the KSA metric. However, the extent to which military medical missions contribute to the readiness of critical wartime specialties has not been evaluated using this metric.

Iatrogenic immunodeficiency-associated lymphoproliferative disorder presenting as small bowel perforation.

A woman in her late 50s on mycophenolate for limited systemic sclerosis presented with abdominal pain. Vital signs and investigative evaluations were normal. Cross-sectional imaging identified gastric and small bowel wall thickening, free fluid, and pneumoperitoneum.

Simple signage and targeted education can lead to process improvement in acute appendicitis care.

Introduction: An institution-wide protocol for uncomplicated acute appendicitis was created to improve compliance with best practices between the emergency department (ED), radiology and surgery. Awareness of the protocol was spread with the publication of a smartphone application and communication to clinical leadership. On interim review of quality metrics, poor protocol adherence in diagnostic imaging and antimicrobial stewardship was observed.

Conflict resolution styles and skills and variation among medical students.

Background: Conflict is inevitable on healthcare teams, yet few professional school curricula teach or assess conflict resolution skills. Little is known about the variation in conflict resolution styles across medical students and how these styles might impact conflict resolution skills.

Methods: This is a prospective, single blinded, group randomized quasi experimental trial to assess the impact of knowing one's own conflict resolution style on conflict resolution skills in a simulated encounter.

A Decade of Surgery Aboard the U.S. Naval Ship COMFORT (T-AH 20).

Introduction: The U.S. Naval Ship COMFORT has performed six humanitarian assistance and disaster relief mission since 2007.

Risk Factors for Urgent or Emergent Cholecystectomy Mid-workup for Symptomatic Cholelithiasis.

Background: Patients who undergo cholecystectomy often do so for diagnoses related to the sequelae of gallstones. Many patients present acutely, requiring urgent removal due to complications of cholelithiasis. This study aims to characterize the patient population likely to present acutely during ongoing workup for cholelithiasis to better identify those who may benefit from expedited care.

To Scan or Not to Scan: Development of a Clinical Decision Support Tool to Determine if Imaging Would Aid in the Diagnosis of Appendicitis.

Background: Appendicitis is one of the most common surgically treated diseases in the world. CT scans are often over-utilized and ordered before a surgeon has evaluated the patient. Our aim was to develop a tool using machine learning (ML) algorithms that would help determine if there would be benefit in obtaining a CT scan prior to surgeon consultation.

Grilling pains: case series of four patients needing operative intervention after accidental ingestion of a wire bristle.

Accidental ingestion of a grill brush wire bristle is a rare event. Retrieval rarely requires surgical intervention as the wire typically causes symptoms above the gastro-oesophageal junction and can frequently be removed endoscopically. There are few reported cases of gastrointestinal injury due to ingestion of wire bristles lodging past the gastro-oesophageal junction in adults.

Vital Conversations: An Interactive Conflict Resolution Training Session for Fourth-Year Medical Students.

Introduction: The AAMC has recognized the importance of effective teamwork and collaboration. One core Entrustable Professional Activity emphasizes creating a climate of mutual respect and trust and prioritizing team needs over personal needs, which leads to safe, timely, effective, efficient, and equitable patient care. Relationship conflicts, specifically, are associated with decreased productivity, complex information processing, and work satisfaction.

Keeping tabs: Reducing postoperative opioid prescriptions for patients after breast surgical procedures.

Background: As the opioid crisis continues, it is critical that health care providers ensure they are not overprescribing opioid medications. At our institution (Walter Reed National Military Medical Center, Bethesda, MD), postoperative patients after breast surgeries are discharged with variable amounts of opioid medications. However, many patients report minimal opioid use.

Instituting a Surgical Skills Competition Increases Technical Performance of Surgical Clerkship Students Over Time.

Introduction: Surgical skills training varies greatly between institutions and is often left to students to approach independently. Although many studies have examined single interventions of skills training, no data currently exists about the implementation of surgical skills assessment as a component of the medical student surgical curriculum. We created a technical skills competition and evaluated its effect on student surgical skill development.

Extracorporeal Membrane Oxygenation and Interfacility Transfer: A Regional Referral Experience.

Background: The number of adults referred to high-volume centers for extracorporeal membrane oxygenation (ECMO) is increasing. Outcomes of patients requiring transport are not well characterized, and referral guidelines are lacking. This study describes the experience and outcomes of a single high-volume center.

New modalities of neurostimulation: high frequency and dorsal root ganglion.

Purpose Of Review: Neurostimulation is a well tolerated, cost-efficient, and effective method to treat chronic pain. Although spinal cord stimulation (SCS) has been shown to help patients, newer modalities such as burst, kilohertz-frequency, and dorsal root ganglion stimulation may provide greater pain relief, fewer paresthesias, and better outcomes.

Recent Findings: Burst stimulation, programed as five-impulse burst at a frequency of 500 Hz, delivers more charge per second than conventional stimulation.

Extending the search for neutrino point sources with IceCube above the horizon.

Point source searches with the IceCube neutrino telescope have been restricted to one hemisphere, due to the exclusive selection of upward going events as a way of rejecting the atmospheric muon background. We show that the region above the horizon can be included by suppressing the background through energy-sensitive cuts. This improves the sensitivity above PeV energies, previously not accessible for declinations of more than a few degrees below the horizon due to the absorption of neutrinos in Earth.

Limits on a muon flux from neutralino annihilations in the sun with the IceCube 22-string detector.

A search for muon neutrinos from neutralino annihilations in the Sun has been performed with the IceCube 22-string neutrino detector using data collected in 104.3 days of live time in 2007. No excess over the expected atmospheric background has been observed.

Limits on the high-energy gamma and neutrino fluxes from the SGR 1806-20 giant flare of 27 December 2004 with the AMANDA-II detector.

On 27 December 2004, a giant gamma flare from the Soft Gamma-Ray Repeater 1806-20 saturated many satellite gamma-ray detectors, being the brightest transient event ever observed in the Galaxy. AMANDA-II was used to search for down-going muons indicative of high-energy gammas and/or neutrinos from this object. The data revealed no significant signal, so upper limits (at 90% C.

Search for pi(0)-->nu(mu)nu(mu) decays in the LSND detector.

We observe a net beam excess of 8.7+/-6.3(stat)+/-2.
